1. "EDITORS CORNER" 

Hi NT/2000 Pro's,

This weekend I'm flying to Paris and Amsterdam to visit the Sunbelt
Offices in Europe. That means the next issue may be a day or two 
later than normal. And after hesitating for a long time I have taken
the step to change from one ISP to another for my home office. The
cable modem I had with GTE was technically fine, but their mail
servers continued to have problems. I'm a big fan of the old rule
'if it ain't broke don't fix it' but this time I just _had_ to!

A few of my colleagues used the Time Warner's road runner cable 
modem service and had no problems what so ever for extended periods 
of time. More over, they provide tech support through the weekends 
(GTE did not) and that is what I needed for my home office. So I 
grudgingly made the change, but it went surprisingly well.

Instead of GTE's fixed IP address system, Time Warner uses DHCP 
to allocate IP addresses dynamically which is actually easier and
seems to work just fine for a large scale project like this. There
are thousands of cable modems in this area. But again, as a consumer
I chose for GOOD SUPPORT as my main reason to move. And that's why
Sunbelt offers you mainframe quality support as well. We can get
you 24x7, all year round if you need that.

OOOPS: Last Issue I wrote: "The software that did the web-clustering 
was the IP load balancing built into Win2K called WLBS." But.. WLBS 
was on NT4.0, now it's called Network Load Balancing Service (NLBS).

Warm regards,

2. TECH BRIEFING:

* MS CLUSTERING ARCHITECTURE TERMS DEFINED

(Wondered where the term WolfPACK came from? Get ready to take notes, 
make some sketches for yourself and learn some new words. Stay with 
me now and take a sip of coffee!)

So, your company expands in the booming economy. You need to manage
50 or 100% growth every 12 months. How the heck are you going to do
it? We're talking Architecture here. Better plan well ahead, because
if you get stuck in a non-scalable situation it can cost a lot. If
you plan to outsource or co-locate, better make sure that your co-lo
provider has their architecture mapped out right.

You must be able to start small and grow as the demand increases.
If you run an e-commerce site you'd better be able to grow FAST as
well. You can grow by Scaling UP or by Scaling OUT. Upscaling is
replacing your existing servers with new, bigger ones. Outscaling
means you add more servers to the existing ones.

This last approach has created the expression 'buying computing by
the slice' and 'building systems from CyberBricks'. Let's define 
one more term: FARM. This is the collection of all the servers,
applications and data at a particular site. The whole farm is
managed as a unit, with common staff and management policies.

For disaster tolerance, a farm needs to be replicated at one or
more geographically remote farms. You can use Double-Take for that
for instance. A collection of farms is called a GEOPLEX. If a
farm fails, the other(s) continue to provide the services till the
failed site is repaired. 

You can grow a farm in two ways: CLONING, or PARTITIONING. You can
CLONE a service on many replica nodes that each run the same data
and software. Requests are load balanced between the clones. You
can load balance the requests externally to the clones with a so
called 'IP sprayer' like CISCO LocalDirector. Or you can have the
clones do it between themselves internally with an 'IP Sieve' like
the built-in Network Load Balancing Server.

If you have a bunch of clones that do the same work, in MS lingo
these are called RACS. (Reliable Array of Cloned Services). Cloning
and RACS offer you both scalability and availability: one clone
dies and the others take over if you have the right setup defined.
It's a great way to add CPU power, network bandwidth and storage
bandwidth to a farm.

PARTITIONS grow a service by duplicating the hardware and software
but by dividing the data among the nodes. For example mail servers
would partition by mailboxes, or sales application systems would 
partition by different geographic sales territories. Partitioning 
does not get you better availability as the data is only stored 
in one place. The solution for that is to create them as PACKS. 

You can implement these PACKS as active-active (both take over for 
each other) or active-passive where one is a hot-standby but does 
nothing. Again, Double-Take allows you to set up both of these.
And, to stay consistent and invent another word, these are called
Reliable Arrays of Partitioned Services (RAPS).

So now, you can build a multi-tier architecture using both RACS and
RAPS with a front-tier that interfaces with your users (website for
instance), a middle-tier that contains your business logic, and
a data-tier (SQL 70.0 servers) that manages your storage. 

Here is a Glossary that gives you these terms tightly defined.

Active-Active: A pack or geoplex architecture in which all members 
are actively processing some work (in contrast to active-passive). 

Active-Passive: A pack or geoplex architecture in which one member 
is actively processing work and the other member(s) is passively 
waiting for fail-over (in contrast to active-passive). 

Availability: The fraction of the presented requests that a system 
services within the required response time.

Clone: A replica of a server or service. The clones of a service are 
called a RACS. Requests are distributed among the clones within a RACS.

CyberBrick: The unit of hardware growth in a farm, often it is a 
commodity system that is added to a RACS or RAPS.

Fail-over: A partition may fail on one node and be restarted on a 
second node of a pack, and a RACS or RAPS may fail on one farm of 
a geoplex and be restarted on a second farm of a geoplex.

Farm: A site containing many servers and services, but managed as 
a single administrative entity. A farm contains RACS and RAPS. A 
farm may be part of a geoplex.

Geoplex: A farm that is replicated at two or more sites, so that if 
one site has a catastrophic failure, the second site can service 
the load and thereby provide continuous availability.

Load Balancing: The process of distributing requests among clones 
of a RACS and distributing partitions among members of a pack in 
order to provide better response time.

Pack: A collection of servers that can each host a partition. 
When a partition?s current server fails, the partition fails over 
to another member of its pack. Packs improve availability.

Partition: A part of a service that has been divided among a RAPS. 
Each partition services a specific part of the overall service. 
Mail servers and database servers are often partitioned in this way.

RACS (Reliable Arrays of Cloned Services): A collection of clones 
all performing some service. Requests are directed to the RACS, 
and processed by one of the clones. The RACS is managed as a single 
entity.

RAID (Reliable Array of Independent Disks): A group of disks that 
are aggregated to improve availability, bandwidth, or management.

RAPS (Reliable Arrays of Partitioned Services): A collection of 
clones all performing some service. Each request to the RAPS is 
directed to the appropriate partition and processed by that partition. 
The RAPS is managed as a single entity.

Scalability: The ability to grow the power or capacity of a system 
by adding components.

Scale Up: Expanding a system by incrementally adding more devices 
to an existing node, typically by adding cpus, disks, and NICs to 
a node.

Scale Out: Expanding a system by adding more nodes, complete with 
processors, storage, and bandwidth.

Shared Disk: A pack, clone, or geoplex architecture in which disks 
and state are shared among the services. In a packed partitioned 
architecture, the disks may fail-over when the partition migrates 
to a new member of the pack.

Shared Nothing: A pack, clone, or geoplex architecture in which 
disks and state are not shared among the services ? rather the state 
is replicated at each clone or pack member. In a packed partitioned
architecture, the disks do not fail-over when the partition migrates 
to a new member of the pack, rather the partition uses the local 
replica of the state.

Transparency: In general hiding implementation details from the 
clients. In the context of scalability, hiding the partitioning, 
cloning, and geoplexing from the clients. Client requests are 
automatically routed to the correct partition or clone. 

All of this comes out of an extremely useful (much more in detail)
white-paper that is available from Microsoft Research. FTP it from:
http://research.microsoft.com/scripts/pubs/view.asp?TR_ID=MSR-TR-99-85

3. "NT RELATED NEWS" 

* QUICK OVERVIEW OF W2K PRODUCT FAMILY

I created a grid with the basic data you need to understand the 
differences between the different flavors, and a recommendation of
the actual hardware you need to run it in a production environment.
The so called 'minimum requirements' for the environment that MS
includes make no sense what so ever. I have no clue why they print
numbers like a 133Mhz CPU for W2K Advanced Server in their overviews.
Anyway, the mysteries of Public Relations are over my head. Here is
the simply grid I created for you with the basics and our viewpoints.

* MICROSOFT SITE THWARTS TUESDAY HACK ATTEMPT

MS said late Wednesday that hackers had tried to topple its Web site, 
but had done little damage. The Tuesday morning ambush did not crash 
the Web site as in other cases, but caused a brief slowdown of about
3 to 7% in the initial page viewing. Basically, they have SO much
capacity that it's very difficult to shut them down, and the W2K OS
they are running the site on, apparently held up to against the attack.

------------------------------

* WANT TO SEE THE GUTS OF A W2K MAINFRAME?

The only machine that currently is able to support the full 32 CPU
capacity of Windows 2000 Datacenter in one box is the Unisys ES7000
machine. The specs are interesting, and Redmond has one of these
puppies that they use to tweak their 'big fat flavor' of W2K.

Want to see the guts of this puppy instead of all the slick design
marketing materials? Here are some inside scoop specs: 32 Intel CPU's
intermixing Pentium III Xeon and Itanium 64 bit processors (in groups 
of four). 64 GB RAM, 96 PCI bit slots. All of this interconnected with 
a 32 GB (gigaBYTE per second) crossbar bus. Partitionable in 4 CPU 
increments into different instances of the OS - NT 4.0, W2K, Unix.
But here is the fun, see the hardware goodies I found for you!
